In Germany August 28, 1934 2 Claims.

This invention relates toa container for electrical condensers and is especially adapted to the electrolytic type of condensers having a casing which acts'as one electrode of the condenser, and

I an insulated disc secured to the casing, the disc having an aperture-for the other or central electrode. Condenser casings or containers have been disclosed in the prior art which are provided with a screw-threaded extension piece adapted to se- 10 cure the mounting plates, etc. The forming of a screw-thread, as is known from practice, is a1 ways comparatively complicated. The present invention is concerned with a container for elecn trical condensers, and its purpose is to afford an ll easy and inexpensive mode of mounting the same upon plates or similar supports. This is accomplished according to the invention by that in the opening of the container is fitted a disk having extensions or lugs. The latter for-'securing the yconl tainer are bent toward the mounting plate or else simply turned about a suitable angle. The said disk here disclosed is suitably provided with three lugs formed by stamping and being 120 degrees apart. The condenser may then be-retained in- Il dependntly of the central electrode. It may be mentioned also that the container here disclosed is particularly suited for the so-called dry electrolytic condensers. y The drawing shows an exempliiied embodiment l) of the invention.

Fig. l is a section through the container; Fig. 2 shows a detail insection, and Fig. 3 shows the disk provided with the lugs;

Fig. 4 shows the method of retaining the con- I5 denser to a plate or similar mounting support by bending the lugs at an angle.

Inside the metallic container I is the condenser body 2.v The former has a nick or depressed rim I upon which the insulated closure disk 4 is laid.

40 Upon the latter is the metallic disk 8 which is ring-like in shape with lugs or extensions 5, 6, 1,

the latter being staggered in reference to one another an angle of 180 degrees. The border or rim 9 of the container I is crimped or rolled over in such a way that it presses the disks 4 and 8 against the nick 3 thereby obtaining locking of the plates in position. The securing of the container upon any suitable mounting plate, not

shown, is effected, by providing suitable holes or Il slots in the mounting plate located in a position similar to that of the lugs 5, 6, 1, shown in Fig. l,

lug 'I not appearing thereon. When mounting the condenser on the mounting plate, the lugs 5, I and (C1. ns-sis') l are pushed through the holes and then bent away from the center of the condenser over towards the mounting plate I2. Occasionally, a mere twisting of the said lugs about a certain angle will suiiice as shown in detail by Fig. 4. I0 l denotes a connecting electrode for the condenser body which is brought out of the vessel by way of the lead-in II. The second pole or connection, as known in the art, may be formed by the very container I. l0

I claim: n

1. A container for an electrical condenser comprising a metallic cylindrical casing acting as one terminal of the condenser closed at one end and 'open at the other end, said casing having a de- 15 pressed rim near the open end, another terminal centrally located at the open end of said casing, an insulated disc closing the open end oi said casing, said insulated disc resting against said depressed rim, a mounting member for said con- 90 denser, a metallic disc having a plurality of extension members, each member passing through an opening in said mounting member and being twisted about a center angle on the opposite yside from which said condenser is mounted for mount- 25 ing said condenser independently of the other terminal, said metallic disc located on said insulated disc, the open end of said condenser casing being bent over to retain said insulated and metallic discs in place on said'condenser. 3"

2. A container for an electrical condenser comprising a metallic cylidrical casing acting as one terminal of the condenser closed at one end and open at the other end, said casing having a depressed rim near the open end, another terminal centrally located at the open end of said casing, an insulated disc closing the open end of said casing, said insulated disc resting against said depressed rirn, a mounting member for said condenser, a metallic disc having three extension 4U members projecting inward toward the center of said metallic disc, each extension member passing through an opening in said mounting member and being twisted about a center angle on the op posite side from which said condenser is mounted 45 y for mounting said condenser independently of the other terminal on said mounting member, said metallic disc located on said insulated disc, the open end of said condenser casing being bent over to retain said insulated and metallic discs in place on said condenser.
